It’s a requirement of the National Construction code. Under the code, window openings on the second floor need to be less than 12.5cm or fitted with fall-prevention screens.

It’s all about performance. Thermally broken frames separate the interior and exterior parts of the frame with a less conductive material so they help keep you warmer in winter and cooler in summer. Standard frames don’t have this feature.

Standard glass is uncoated. Low-e is standard clear glass which has a special coating on one side. Low-e glass can reduce heat conduction by around 30% compared to standard glass. It also cuts down on glare and protects the interior of your home from UV rays.

The first thing you need to think about is whether you want the same finish inside and out (single finish) or different finishes on the inside and out (dual finishes). When you’ve done that, it’s time to let your imagination run riot with a huge palette of colour choices.

Of course! Here are our top tips:

• Keep your window surrounds clean, giving special attention to the sashes where dirt and grit usually accumulate, then give the sashes a good vacuum.
• Give your spring locks a spray with penetrating lubricant. This helps stop the springs stiffening.
• Did you know you can use car wax on your frames? It helps reduce dirt and grim and keep your windows shining.
• Fight rust and corrosion by using a silicone lubricant after you’ve cleaned your windows.
• Scrub the frames with a mix of one-cup mild detergent and one-litre of wate. This will protect from pitting and oxidation.
• For sparkling window glass, spray with window cleaner and use newspaper to wipe it down. Use a circular motion for best results.
